Hemophilia is caused by several genetic factors; one, a recessive allele of an x- linked gene, is the subject of this problem. assume that a man with hemophilia marries a normal woman whose father had hemophilia. what is the probability that their first son will have hemophilia?

It’s recessive. The mother who is a carrier is heterozygous, but she does not have the disease. The only offspring who have the disease are the boys who inherited one mutated gene.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
